Reaction Steps

The tetralone (10 g; 56.8 mmol) was dissolved in 200 ml of toluene. To the solution then were added 13.0 ml (0.117 mol) of N-methylpiperazine followed by 25.1 g (0.13 mol) of p-toluenesulfonic acid. The mixture was stirred at reflux with constant removal of water. After 2 hours, the mixture was cooled to room temperature, and the volatiles were removed in vacuo to give 3-(N-methylpiperazinyl)-5-methoxy-1,2-dihydronaphthalene as a reddish-orange sludge.
